%N Prime-indexed primes p such that Lucas(p) is prime.
%F a(n) = prime(A123677(n)).
%F a(n) = prime(prime(A123678(n)).
%e 17 = A000040(7), with 7 itself being a prime, and A000032(17) = 3571, a prime, thus 17 is included in this sequence.
%Y Cf. A000032, A000040, A123677, A123678.
%Y Subsequence of A006450. See also A168033.
